Computer Shutdown Issue

[Zelic]

Hey there (new to the forums).

I am having an issue playing games (mostly higher end games BC2 and the like) I can generally play them for 5 or so mins before computer shuts down. In games such as rift this will not happen until there are many things going on.

I recently purchased some upgrades for PC and had issues with overheating on my CPU but got that replace and now its fine, but I still getting crashes.

Specs:

Gigabyte GA-890FXA-UD5 Motherboard
AMD Phenom II x4 965 Black Edition CPU
8GB Corsair RAM
650W PSU
GTX275 GPU Leadtek
2x 19" ViewSonic Monitors


The only thing I can think of is that maybe the PSU isn't sufficient enough to support this setup.

Any help would be much appreciated cheers.

What is the brand name and model number of your power supply? A 650w PS should be enough if it's a quality unit built by a reliable manufacturer.
